No, there is no knowing here. Its an opinion that many hold for lack of something better. The Climate will change no matter what we do. If we disappeared as a species today, the climate would still change. Because it always had since the first unicellular organisms populated the primitive oceans billions of years ago. This planet is the way it is. Humans are good at adapting so thats what we should do instead of putting it in the freezer. Let nature do its thing.
What if we knew the U.S. economy was poised to lose hundreds of billions of dollars in value in coming years, resulting in 10 percent of our gross domestic product being wiped out?
